In order to accurately meet the different business needs of users, it is necessary to effectively manage various services, and it is necessary to unify the addressing of each service. Service addressing is a logical symbol for identifying services. It is mainly used to implement positioning and routing functions for services.

Currently in telecommunications networks, a stream of water numbers is usually used to characterize a service. For example, to subscribe to a service with a mobile phone, you need to send XX to yyyyyy, where yyyyyy is a business address. This type of addressing does not effectively represent the characteristics of the service, and it is inconvenient to manage and apply thousands of services in a wide variety of services.

On the existing Internet, when a user needs to access the URL of a domain name, the domain name resolution request is usually sent to the domain name server. After the resolution is successful, the domain name server returns the IP address corresponding to the domain name to the user, and then routes to the Internet. The IP address corresponds to the server. This type of routing does not allow the service provider to have access control over the services it provides. . ' Invention content

In a specific implementation of the present invention, the service network is divided into multiple subnets, and the fields required for addressing are determined according to the division of the subnet, and the addressing fields conforming to the addressing specification are generated according to the service information, and the address fields are combined. Generate the address of the service. In order to generate each address field conforming to the addressing specification according to the service information, an addressing identifier database is established, and the main identifiers of the service provider identifier, the service identifier, the service feature list, and the like are stored in the address identifier database. One or more aliases. In this way, the subnet information and service feature information corresponding to a certain service can be converted into the corresponding main identifier by using the information stored in the addressing identifier database, thereby using the address field of the service.

In order to realize automatic addressing of the service, a service providing module and an addressing field generating module are set in the service addressing system, and the addressing field generating module generates each addressing field according to the addressing specification according to the service information provided by the service providing module. And combine them to generate a business address.

Applying the service addressing method of the present invention to the service subscription process, the service subscription address information may be generated according to the service information in the user service request, and then all the service address lists that meet the service subscription address information are transmitted to the user, so that the user is enabled. Easily select the desired service address to route directly to the business service. The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Referring to FIG. 1, an implementation process of a service addressing method in an embodiment of the present invention includes the following steps: Step 101: Determine a service addressing field and an addressing specification.

Those skilled in the art will recognize that when a service provider deploys a service, it needs to address the service. Service addressing can usually be divided into any number of fields, each field can be independently determined, and then each field is combined into the address of the service.

The service network can be divided into multiple subnets according to requirements. The service network is a primary network, and the service subnet of the service provider is a secondary network. The specific service service service subnet is a three-level network, as shown in Figure 2:

S00 is a client, S01 and S02 are service subnets of different service providers respectively, S03 and S04 are different service service subnets respectively, and S05 is a service core network, which is used to provide between service subnets. Connected to each other.

For example, a service provider weathersp provides weather forecasting service weather, and the weather forecast can be provided by various means such as email, short message, and multimedia message. Then, it is considered that the service provider weathersp is the sp service subnet and its weather business. The network is the weather service subnet, and the specific services provided by email, short message, and MMS correspond to the three services. .

According to the division of the above network subnets, it can be determined that the addressing scheme shown in Table 1 below is used for each type of service:

Table 1 :

Service Provider ID SP Service ID SID Service Feature List FeatureList For a specific unique service, the addressing is divided into a prefix and a suffix, where the prefix includes the service provider ID and the service ID, and the suffix includes the service feature list. The lengths of the service provider ID, the service ID, and the service feature list may be fixed. Of course, the special separator may be used instead of being fixed. For each service provider, a globally unique ID will be assigned; for each specific service provided by the service provider, a unique ID within the service provider subnet will be assigned; the service feature list mainly includes a service subnet. Ability to distinguish basic features of various services, such as enabler in OMA (Open Mobile Alliance) The features provided by the enabler components such as the SCF (Business Capability Feature) in Parlay.

Of course, depending on the application requirements, two fields or more than three fields may be used for service addressing. The definition of each field is not limited to the above network level, and the length of each field can be arbitrarily set. . Once the required fields for addressing and the length of each field are determined, each service is addressed according to this specification to ensure that the service can be found correctly based on the address.

Step 102: Obtain service information and service feature list information, where the service information includes at least a service provider identifier and a service identifier.

If the service itself knows the service feature list information, the service feature list information can be directly used to generate the suffix of the service address; if the service itself does not know the service feature list information, the corresponding service feature information needs to be invoked according to the service deployment operation. Way to generate its business feature list information.

For example, if you need to address the "Shenzhen Weather" service provided by the service provider "weathersp", you need to provide the service provider ID and service ID. Of course, you need to provide the service feature list information. In this example, the service provider ID is "weathersp" and the business ID is "Shenzhen weather". If the service itself knows its service feature list information, for example, the service feature is a short message service; if the service itself does not know its service feature list information, it needs to generate the service feature according to the service deployment operation and the corresponding service feature information. List information, for example, for a specific "Shenzhen Weather" service, it is found that it invokes a "short message" providing unit (a specific feature providing unit), that is, a short message method to provide a service, so that a service feature list can be generated. "short message".

Step 103: Generate respective addressing fields conforming to the addressing specification according to the service information and the service feature list information.

In order to uniquely identify different services in each subnet, you need to set a unique global identifier, that is, the primary identity, for each service in each subnet.

For example, for the division of the above service subnets, each service provider ID and service ID need to be uniquely determined. To this end, an addressing identifier database can be established in which all legal service provider ID information and service ID information and service characteristic information are stored. There is a unique ID for each service provider and each business and business feature. Each ID may correspond to one or more aliases.

For example, the address identification database shown in Table 2 stores multiple service provider IDs, service IDs, and service feature ID information.

Table 2

Of course, the way in which the various information in the addressing database is stored is not limited and can be flexibly arranged as needed.

When a new service is added to the operation, the primary identifier of the service information corresponding to the subnets of the service and the corresponding one or more aliases are added to the address identification database; when the original service is canceled and the system does not need When the service information is used, the main identifier of the service information corresponding to the subnets of the service in the address identifier database and one or more aliases corresponding to the service information of the subnets are deleted; The service feature information is added to the address identification database; when the specific service is canceled and the feature information of the service is not required to be referenced in the system, the feature information in the address identification database is deleted.

When generating the address fields conforming to the addressing specification by using the information stored in the addressing identifier database, firstly, the service information of the service in each subnet is extracted from the obtained service information, and then the service information is used to match the addressing. Identify the primary ID of each service stored in the database and its corresponding one or more aliases, and obtain the primary identity and service feature column of each subnet corresponding to the service. Table. The main identifier and the service feature list of the subnet corresponding to the service are used as the address fields of the service. For example, for the "weather" service provided by the service provider "weathersp" through "MMS" as the "Shenzhen", the address field is obtained by querying the address identification database: 333, 4444, 35.

If multiple services request addressing at the same time, the same serial number is generated for each address field generated by the same service, so that when the service address is generated, a combination of different service addressing fields is not generated, and an incorrect addressing is generated.

Step 104: Generate an address of the service by combining each address field corresponding to the same service. As mentioned above, the length of each addressing field may be the same or different, and may be a fixed length or an unfixed length. For the fixed-length addressing of each field, when the field combination is performed, the fields may be separated by a separator, or may not be isolated, and the length of each field can clearly know the characteristics of each field of the service; For unfixed addressing, when field combinations are made, the fields must be separated by a separator to effectively distinguish the fields. For example, according to the address fields obtained above, each address field corresponding to the same service is separated by a separator, and the service address is combined to generate: 333.4444.35.

Referring to FIG. 3, the service addressing system in the embodiment of the present invention includes:

The service providing module Sl, the addressing module S2, and the identifier generating module S4. The service providing module S1 is configured to provide service information; the addressing module S2 is configured to generate each addressing field that conforms to the addressing specification according to the service information; and the identifier generating module S4 is configured to combine each address field to generate a service address.

The addressing module S2 includes: an addressing identifier database S20, a receiving unit S21, and an addressing field generating unit S22.

The addressing identifier database S20 is used to store the primary identity of each service and its corresponding one or more aliases.

After the service providing module sends an addressing request to the addressing module, the receiving unit classifies the service information in the addressing request, and carries the extracted service information with the serial number of the corresponding addressing request; and then submits the information to the editing The address field generating unit generates, according to the information stored in the addressing identifier database, various types of service information extracted by the receiving unit to each address field conforming to the addressing specification. The generated address fields are combined by the address generation module to generate services according to the agreed order. Address.

Corresponding to the division of the network shown in FIG. 2, the service provider processing sub-unit S221, the service identification processing sub-unit S222, and the service feature list processing sub-unit S223 may be respectively set in the addressing field generating unit S22, by these three sub- The unit generates a service provider ID field, a service ID field, and a business object list field according to the corresponding information, respectively. Of course, the same unit can also process the business information to the conversion process of these three fields in turn.

It is assumed that the service provider ID field, the service ID field and the business object list field are generated by the three sub-units according to the corresponding information, and the addressing process of the system is as follows:

First, the service providing module sends an addressing request to the addressing module, and the service provider ID, the service ID, and the service feature list are transmitted to the addressing module. After receiving the addressing request, the receiving unit in the addressing module extracts each service parameter, and then passes each parameter to the relevant processing unit to obtain a specific addressing of each field. The service provider processing sub-unit S221, the service identification processing sub-unit S222, and the service feature list processing sub-unit S223 respectively query the addressing identifier database according to the received service provider ID, service ID, and service feature list information, and obtain respective matching addresses. The standard information, that is, the alias ID is replaced with the primary ID; if there is no corresponding record, each processing unit triggers an exception.

Reason.

Referring to FIG. 9, the implementation process of the service subscription method in this embodiment includes the following steps: Step 901: Acquire service information in a service application request.

When the user wants to use or query a certain service but does not know the specific address of the service, the service request can be submitted to the service provider, and the user specifies the required service information in the service application request, for example, the service provider ID. Information, business ID information, etc.

Step 902: Generate a coded field corresponding to the address specification of the corresponding service subnet according to the service information.

Similarly, an addressing identifier database can be created in which the primary identity of each service and its corresponding one or more aliases are stored. Extracting the service information of the service from the service information provided by the user, and using the service feature to match the primary identifier of each service stored in the address identification database and one or more corresponding aliases thereof, the service corresponding to the service can be obtained. The main identification of each level, and the various addressing fields of the business.

If multiple services request addressing at the same time, the same serial number needs to be marked for each address field obtained according to the same service, so that the combination of different service addressing fields is not generated when the service address is generated, and the wrong addressing is generated.

Step 903: Combine the coding fields of the corresponding service subnet to generate service subscription address information. According to the predetermined addressing specification, when the field combination is performed, the fields may be separated by a separator, or may not be isolated, and the characteristics of each field of the service can be clearly known by the length value of each field.

Step 904: Transmit all service address lists that meet the service subscription address information to the user;

After the service providing module sends an addressing request to the addressing module, the receiving unit classifies the service information in the addressing request, and carries the extracted service information with the serial number of the corresponding addressing request; and then submits the information to the editing The address field generating unit generates, according to the information stored in the addressing identifier database, the various types of service information extracted by the receiving unit to each addressing field conforming to the addressing specification. The generated address fields are combined by the address generation module in the agreed order to generate a service address.

' Service provider processing subunits can be set separately in the addressing field generation unit S22

The S22K service identifier processing sub-unit S222, wherein the two sub-units respectively generate a service provider ID field and a service ID field according to the corresponding information. Of course, the same unit can also process the business information to the conversion process of these two fields in turn.

When the user applies for the service, the user equipment sends a service request request to the user agent, and the user agent transmits the service request request to the addressing module, and generates each address field, and then the service address extraction module extracts the compliance office from the service pool. Describe the service address list of the service addressing field 0 generated by the addressing module, and return it to the user agent; the user agent sends the service address information to the user equipment, so that the user can select the desired one in the service address list. Business application.

The specific business subscription process is as follows:

1. The user equipment sends a service request request, which carries service provider ID information and service 5 ID information. ^- If the user applies for "Shenzhen Weather" business to "weathersp", the two parameters are carried in the request.

2. The user agent submits a user request to the addressing module.

The receiving unit analyzes the information according to the received request, and extracts the service provider ID information and the service ID information, and distributes the information to the processing sub-units. At the same time, provide A globally unique serial number is given to the request, and the service provider ID information and the service ID information are also appended with the serial number, so that the service address extraction module can find the corresponding information.

3. The receiving unit extracts the service provider ID information and adds the upper serial number to the service provider processing subunit. The service provider processing sub-unit queries the address identification database according to the received service provider ID information, and obtains data information conforming to the addressing specification. For example, "seahtersp" is converted to a unique number "333".

At the same time, the receiving unit extracts the service ID information and adds the upper serial number to the service ID processing subunit. The service ID processing sub-unit queries the address identification database according to the received service ID information, and obtains data information conforming to the addressing specification. For example, "Shenzhen Weather" is converted to a unique number "4444".

4. The service provider processing sub-unit transmits the data information conforming to the addressing specification to the service address extraction module, where the serial number assigned by the receiving unit is carried.

At the same time, the service ID processing sub-unit transmits the data information conforming to the addressing specification to the service address extraction module, where the serial number assigned by the receiving unit is carried.

The service address extraction module processes the received service provider information and service ID information, and combines the information with the same serial number.

5. The service address extraction module passes the combined service application information to the service pool.

Based on the received application information, the service pool extracts services that match the service provider ID information and service ID information and form a service list. For example, if the business that meets the requirements is as follows: "333.4444.15", "333.4444.35", "333.4444.58", then these three businesses will form a business list.

It is assumed here that the "location feature" (business needs "location" support) flag is "5", "short message feature, (business needs "short message" support) flag is "8", "mMS feature" (business needs) MMS ,, support) flag is "3", "EMAIL feature" (business needs "EMIAL" support) flag is "1".

6. The business pool passes the business list to the processing module.

7. The service address extraction module passes the service list to the user agent.

If necessary, the user agent may also filter the service list according to the received service list and according to the characteristics supported by the user agent. User agent must be able to understand this The service is addressed, and the list of service features in the addressing is understood, and it knows the service features supported by the user equipment. If the required feature of the service in the service list is not supported by the user equipment, the service will be specially processed, for example, it may be deleted from the list, or may not be deleted but added to the other.

For example, if there is a "5 - 0" record in the user agent indicating that the user agent prohibits anyone from accessing its location information, then all services in the service list will be filtered. For example, if there is a "3 = 0" record in the user agent, the user device does not support MMS, then the "333.4444.35" service in the service list will be filtered out.

8. The user agent transmits the filtered service list to the user device.

9. The user can select one of the services he needs in the business list as he wishes, and apply for the business.

10. The user agent can directly route to the service to apply according to the service address selected by the user.

It can be seen that with the present invention, it is convenient for the user to query the required service and at the same time facilitate the management and use of various services.

Based on the above service addressing and service subscription mode, the present invention also provides a method for service routing. In order to shield the underlying network, the service network is separated from the bearer network, and a service router is provided at the service network layer. The function of the service router mainly completes the service routing and addressing functions in the service network. By identifying the address of the service, the next hop in the routing process is known. The present invention is provided with a service router in each service subnet, and resources in the access service subnet must pass through the service router in the subnet.

Referring to FIG. 11, the flowchart of the implementation of the service routing method in this embodiment includes the following steps: Step 111: The service address field is set to include a service subnet address and a specific service address. As mentioned above, the service addressing fields are determined according to the division of the service subnet. For example, the service network can be divided into two levels of subnets: a service provider service subnet and a specific service service service subnet. In this way, the service address consists of three fields: service provider ID, service ID, and service feature list.

Step 112: When the user accesses the service address, it is routed to the service subnet according to the service subnet address in the service address field in the user service request message, and according to the specific service place therein The address locates the user to the specific business to be accessed.

That is, when the user is in the service subnet corresponding to the service subnet address, the user can be directly located to the specific service to be accessed according to the specific service address; when the user is not in the service subnet corresponding to the service subnet address, The following routing mode locates the user to the specific service to be accessed: First, it is routed to the service provider service subnet through the service core network; then, it is routed to the service service subnet; and the specific service to be accessed is located.

In this way, the hierarchical positioning can be performed at the time of routing. If the service provider prohibits the user from accessing the service provided by the user, the user cannot access the specific service.

In the present invention, routing is performed according to the concept of a service subnet, which refers to the above-mentioned service provider service subnet and service service subnet.

If the service address that the client (client) needs to access is ABC, where A is the service provider ID, B is the service ID, and C is the service feature list. The routing process is as shown in Figure 12: Step 121: Client requests routing to service The address is ABC's business.

Step 122: The request is routed to the service router of the service subnet where the Client is located, and the service router determines whether the requester Client is in the A.B service subnet. If yes, go to step 128; otherwise, go to step 123.

Step 123: If the requester Client is not in the A.B service subnet, the request is routed to the service router of the service provider subnet where the Client is located.

Step 124: The service router of the service provider subnet where the client is located determines whether the requester client is in the A service provider subnet. If yes, go to step 137; otherwise, go to step 135.

Step 125: If the requester Client is not in the A service provider subnet, then the request is routed to the service router of the service core network.

Step 126: The service router in the service core network routes the request to the service router of the A service provider subnet.

Step 127: The service router of the A service provider subnet routes the request to the service router of the A.B service subnet.

Step 128: The service router of the AB service subnet routes the client's request to the service ABC. In the present invention, the next hop problem in the service route is solved by the service router. In order to map the next hop in the service network to the next hop in the bearer network, a proxy is required to implement address mapping.

To implement service routing, a service routing table needs to be stored in each service router, and the service router searches for the next hop service address according to the service routing table.

The flow of routing to the next hop node through the service router will be described in detail below with reference to FIG. The process of routing the node of the service layer (the A node) to the next node of the service (the B node) is as follows: 1. If the A node is a non-service router network element, the service address of the next node (the B node) is obtained according to the configuration in the subnet. If the A node is a service router, ^^ according to the destination service address carried in the message body of the service message, query the service routing table of the node, thereby obtaining the service address of the next node (Node B) of the service route.

The format of the service message sent by the A node is shown in Table 3 below, where the message body also includes the service address of the destination.

table 3:

Node B service layer address message body

2. The A node sends an address mapping request to the Proxy, where the request carries the service address of the Node B, and the Proxy queries the database of the B node according to the received service address of the Node B, and obtains the address of the carrying node of the Node B, and passes the following Table 4 The message shown is replied to the A node.

Table 4:

Node B bearer layer address Node B service layer address Message body

3. The A node sends the service message shown in Table 1 from the service layer of the node to the bearer network layer of the node.

4. The A node routes the user service request message to the bearer layer node corresponding to the B node at the bearer network layer according to the bearer network address corresponding to the B node in the message.

5. When the bearer network layer confirms that the bearer layer address carried in the message is the bearer network address of the node, the B node strips the bearer layer address field and sends it to the service layer of the node.

After the service network layer receives the message sent by the bearer layer of the node, if the service layer address in the message is the service layer address of the node, the service layer address field is stripped to obtain the final message body. In this way, the user can be targeted to the specific business specified by the message body. As shown in FIG. 14, the embodiment of the present invention further provides a routing device 140, where service routing information is set, including:

The routing processing unit 1401 is configured to route user service data to the service subnet according to the set service routing information and the service subnet address in the user service request message, and locate the user according to the specific service address in the request message. The specific business to be accessed.

The routing proxy unit 1402 is configured with a service address and a bearer network layer address mapping table of each node, and is used to obtain a service address and a bearer network layer address of a next hop node of the service route of the node;

The user service request message is sent to the bearer network layer address of the next hop node and the destination service address in the user message through the bearer network layer of the local node, and the user is located in the specific service to be accessed.

While the invention has been described by the embodiments of the present invention, it will be understood that
